The boundary values of a solution to curl E=kE which is tangent to the boundary and has zero flux through the "A-cycle."
This plot shows that the "spurious resonances" are in the lower half plane for the Debye source method applied to a round ball.
This is the boundary value of a eigenfield of the equation curl E=kE on the unit ball.
